What is IDE (PIO mode 3) used for?

IDE (PIO mode 3) is a programmed I/O transfer mode for older Parallel ATA/IDE storage devices, commonly used in legacy desktop or laptop hard drives and CD/DVD drives.

Why convert IDE (PIO mode 3) to byte per second?

Converting to byte per second standardizes the data rate, helping compare legacy device performance with modern units and analyze throughput in embedded systems.

Does the conversion reflect actual data transfer speeds?

No, the conversion indicates theoretical maximum raw throughput and may not reflect actual speeds due to overhead or hardware limitations.
